EBS database servers - end of life

[satish]

Hi Erman,

Our env:

2 node RAC 19.17

We have an ERP Oracle RAC database in which  physical servers reached their end of life. What actions do we need to follow to move to new servers. Can you please advice high level action plan.

Thanks,
SG

Purchase and install & confgure the new environment (Maybe virtualized .. and/or ODA .. or Exadata . Maybe cloud IAAS or PAAS (if there are no regulations)) .. Be aligned with your licenses..

Then prepare for the migration.. Create a migration strategy, prepare SOPs and execute it.

Most probably, you will use dataguard for the DB migration. (unless there is a platform incompatability)
You will install the new GRID, install the RDBMS software and prepare the dataguard flow and do the switchover..Keep your old db up & running in phys. standby mode, keep it sync  (async replication of course) with the new primary for a while (say 10 days..)  
--Just in case, you may need to switch back to your old env due to a reason.
--According to the case, you may run postclone (or autoconfig) in your db and apps tiers. These types of migrations are already addressed in MOS documents.
